Structure of the Turbulent Boundary Layer 来自 ResearchGate 喜欢 0 阅读量: 144 作者: Leslie S. G. Kovasznay 摘要: The turbulent boundary layer can be subdivided into four distinct regions, sublayer, turbulent wall layer, outer region, and superlayer. Each one of these regions is briefly ...
In the paper the results of experimental researches of the structure of turbulent boundary layer on the flexible extensive longitudinally streamlined cylinder are presented. Researches of the wall-pressure fluctuation field by the ensemble of miniature sensors, flush-mounted with the streamlined surface, ...
In this paper, the Laser Doppler Velocimeter (LDV) and Hydrogen Bubble flow visualization techniques have been used to measure the characteristics of turbulent boundary layer flow over riblets surface and observe its coherent structure in the near wall region. The experiment was conducted in a glass...
The effect of mass removal on nominally two-dimensional, normal- shock/turbulent-boundary-layer interactions was investigated experimentally. The flowfield had a freestream approach Mach number of 1.49 and a Reynolds number based on boundary layer momentum thickness of 14,600. Distributed mass removal...
An experimental study is made of the turbulent boundary layer in its interaction with a shock wave, the purpose being to clarify questions connected with the increase in the fullness of the velocity profiles. New systematic data are obtained on the development of the boundary layer, and its str...
Abstract Experimental results are presented for high Reynolds number turbulent boundary layers. A flat plate zero pressure gradient layer has been studied in a new high Reynolds number boundary layer tunnel. Measurements were made of the mean flow in the Reynolds number range of 3.6 × 103<Rθ<...
In this study, the generation of airfoil trailing edge broadband noise that arises from the interaction of turbulent boundary layer with the airfoil trailing edge is investigated. The primary objectives of this work are: (i) to apply a wall-modelled larg
This chapter discusses the simple case of the turbulent boundary layer in a constant pressure field and considers the complex problem of the effects of pressure gradients, and variable wall roughness. The concepts of boundary layer phenomena, in general, and turbulent boundary layers, in particular,...
